JESSE A. B. SMITH, or STAMFORD, FISHER COMPANY, on NEW TYPE-WRITINGMACHINE Application filed January 19, 1929. Serial No. 333,711.

This invention relates to paper-feeding devices for typewriting andsimilar machines, p

and is particularly useful with loose-ply multiple webs. Heretofore,

rinted lines thereon.

According to this invention the usual feed-' rolls are not used, and theclamps and operating mechanism are supported on the carriage, at thefront of and above ,the platen. The clamp-j aws are pivotally mounted inpairs on two rockable rods, which are parallel to each other and to theplaten, the rods having arms which are operative to swing open and torelease the jaws against spring-tension. The stationary jaws normallypress against a plate, fixed to the carriage, while the pulling jaws,located above the stationary jaws, normally clear a bar, which alsoserves as a cut ofi knife. Said bar with its'pulling jaws is carried onswingable arms, which are raise for line-spacing,

to prevent the loose plies .of a multiple-ply web from creeping one overthe other, when fed around theplaten, the longitudinal edges'of thepiles have been joined together in the well-known fan-folded manner, butthis entailed difliculties in controlling the carbons. The employment ofa fanfolded form of work-web required compli- "cated additions to. thestandard typewriter equipment.

The present improvement provides a means for employing the more easilycontrolled and more desirable loose webs of peper and maintaining exactregistry of all the plies during the line-spacing of the plies, andwithout making extensive changes in the typewriter.

This means includes clamps at the delivery side of the platen,co-op-erative to bind the webs together in such a manner as not tointerfere with the manifolding and the linespacing of the loose plies.

In practicing this invention the platen need not be'revolved, but themovement of a line spacing lever operates two 'sets of clamps, one ofwhich is stationary andclamps the lopse plies of the webtogether while aline is typed, and the other of which clamps the plies together andpulls the web around the platen to line-space it. During theseoperations. the clamps will alternately grip and release the plies, thegripping by either set anticipating the release'by the other, wherebythe plies are constantly clamped into registry with one another. Withthis arrangement the plies of a loose-ply Web will not creep one uponanother, which is a fault when loose plies are fed by means of alinespaced platen, and'the use of realigning pins and perforated-pliesis avoided.- Furthermore, a plurality of plies will not skew oil or rundiagonally when advanced, and the manifolding will be correctly anduniformly aligned andspaced. This is an advantage where multiple-plyprinted webs are'used, be-

cause type-impressions on successive forms leased,

opening and release of the jaws, are all. accomplished by movement ofthe spacing lever, which is connected by suitable levers an links. Theclamp-jaws are set to lie just within the margins of the plies, and, asthey directly hold the same, no side-edge gages are required.

In using this invention the lower or stationary clamps will normally beare opened through a clamp-release-lever which locks them open for theinsertion of the loose plies which are rear-inserted around the platenand brought between the open jaws of both sets of clamps, the upper setat this time being normally open. The lower set of clamps is then closedthrough the releaselever, and will firmly bind the plies together whilea line is typed. Upon completion 'of thelatter, the preliminary rearwardmovement of the line-spacing lever for returning the carriage causes thepulling clamps to first grip the'plies, and then opens the jaws of the.-stationary clamps. Further movement of't'he spacing lever raises saidpulling clamps and-'line-spaces the plies, after which said lever isreleased to be restored through spring-tension. I I 7 Beforethespacinglever is restored, the stationary clamps re-close, and thepulling clamps remain closed untilthe lever is rewhen said clamps openand drop to a and are afterwards dropped.

This invention while holding the loose plies in fixed relation to eachother, at the same time holds the interlying carbons in fixed relationwith the plies. For this reason the carbons do not sm udge the paper,and it resharp manifolding on the carbon-copies. This makes it possibleto manifold more copies at one time, because the typing on the addedcopies will still be legible. With this invention rolls of carbon-papermay be employed, instead of using single sheets intermittently pulledforward and back by carbon-carriers.

In the design shownfthe clamps can be used when carbon-sheets arereplaced by carbonribbons, which are horizontally interleaved throughloose plies at the front of the platen. This advantage is gained becausethe clamping devices are so arranged as not to conflict with saidribbons and their holding devices.

while the two device are separate, they are still near together, so thatwide blank spaces or headings are not required between the typing lineand the clamps. The clamps which line-space the paper do so by a directpull above a spring-pressed This is an advantage over feed-rolls whichmerely push the plies because, in the latter case, some of the plies maybelly out between the feed-rolls and said 'spring-pressed device. Thisis caused through friction set up by said device in pressing the pliesagainst the platen, and results in unequal spacing and .poor manifoldingalignment on some of the plies.

vWhen this invention is used, the plies are always stretchedtaut.between the clamps and .the spring-pressed scaleplate, or otherdevlce, which 1s another result that insures uniform alignment andclear-cut type-impressions on all the sheets. Furthermore, because thepaper is pulled from above instead of being pushed from below the typingline, typing can be done nearer to the bottoms of the severed sheets.

Referring to the drawings, 10 indicates a wor -pack that includes aplurality of loose webs of paperinterleaved with webs of carbon that maybe inserted as a unit at the rear of a carriage 12 and directed aroundthe platen 14 by a paper-table and paperdeflector' 11. The upon theusual platen-shaft 15, supported at each end by the carriage-end framesand provided with platen-knobs 16 and a toothed platen maybe supportedplaten-holding detent-wheel 17. The worki deflector 11, to bear againstthe pack and serve as a drag to retard the free advance of the packaround the platen and over the typing line. roller 18 is pivoted at 19upon the free end of an arm 20'hung from a screw 21, threaded into thecarriage-end and provided with a spring 23, tensioned against a pin 23,to force the roller into engagement with the teeth of the wheel todetermine a line-typing position along the face of the platen. The screw21 may be shouldered at 22.to enter a slot 24 and support one end of theplate 25, having a rest 26 fixed thereto, and further supported by aguide-plate 27 secured to the carriage-end. This plate 25'is slidable toset the location of the rest 26 and may then be secured in position bythe screw 21 portion of a slide-bar 28, which, near its forward end, isslidable in a slot 29 that is formed in the carriage-frame. The latteralso supports superposed brackets 30, which are adjustably attachedthrough setscrews 31 and slots 32. 7 Normally, the slidebar is pressed*forward by an anchored spring The guide-plate 27'. also supports therear The forward movement 7 On, the slide-bar-28 is a trip'39 and a lugv 40.. The trip 39 normally abuts the rounded end 41 of a jack-lever 42,which is pivoted at 43 on 'a lifting arm 44 that is pivoted on arotatable lower rod '45. Said lifting arm has an car 46, which isthreaded for a setscrew 47, having alock-nu-t 48. Said set- ,screw 47abuts an arm '49 on said jack-lever 42, and governs the upward travel ofsaid lifting arm when the trip 39 slides rearward ly along the roundedend 41. The lifting arm 44'also carries a stepping lever 50, which ispivoted at 51, has seats 52, and is crossconnected to the jack'lever 42by a contractile spring .53.

The lower rod is journaled at each end in the brackets 30, and carriesan attached lever 54 which is formed with an car 55 that overlies thethereforeraise sald lever but will not pul it down. Said ro'd alsocarries an attached arm 56 having a contractile spring 57, which isanchored to a pin 58 carried by one of the brackets 30. On saidflattened surface on a cam 60. The latter 1s pivoted on a stud 61, whichis carried by one of said brackets, and also has a finger-lever 62. Saidcam 60 is provided with a recess 63 in which there normally rests thebent end of a leaf-spring 64 thatis attached to one of said brackets.

Attached to the lower rod 45 through setscrews 65, are pressure-arms 66and pivotal jaws or clips 67 having bearing-pieces 68. The latter arepositioned through the abutment of said arms 66 on one side andset-collars 69 on the other side.The jaws 67 have convex, ends 70, andmay be formed integral with the bearing-pieces 68." One of the latter,on each jaw, has an ear 71, which maybe integral, and is threaded for anadjustable abutment or set-screw 72 having a lock-nut 7 3f Coil-springs7 3 normally force the pressurearms 66 towards the set-screws 72 andkeep the saws under tension.

At the free end of the lifting arm 44 is a stud or roller 74, which canoverride a cam 75 that is carried on a lever 76. The latter is swingableon a pivot 77, which is carried by one of the brackets30. The lever 7 6'also has a pivot 78, which supports one end of a link arm 44. The lattercan l threaded for\ an adjustable abutment or setrod 45 also is an at- 1tached cam-lever 59, which normally abuts a lock nuts 119, said screwsacting able rest for the table in connection with the br ackets 30. Saidbrackets have slots 120,

overthrow of the lever,

88 which are secured to a shaft 89 journaled in the brackets 30, and isheld therein by said hubs. The swingable arm is formed with an extension90; having a plurality of holes 91, which may be identified by numerals,as shown in Figure 5. Said arm 85 also has a stud 92, on which ispivoted a spacing arm 93, having a stud 94, carrying a roller 95. Alsoattached to said arm 93 is a housing 96 which contains a plunger 97 toregister with said hol'es, and includes a shank 98 that extends throughsaid housing, and a button 99 riveted thereon. A coil-spring 100 tendsto force the plunger out of the housing, while said button limits suchmovement. For purposes of shorter description, the parts 96', 97, 98, 99and 100' are called a latch, which is given the number 101.

The upper rod 83 carries pressure-arms 102, which are adjustable thereonthrough setscrews 103. Said rod also carries pivotal jaws or clips 104,havin bearing'pieces and convex ends 106. he? of the bearing-pieces oneach jaw may have an ear 107, which is screw 108 having a lock-nut 109.Both said bearing-pieces and said ears may be integral with the jaws.Coil-springs 110 normally the set-screws 108 and keep the jaws undertension. Set-collars 105 are also provided to position saidbearing-pieces.

Carried by the upper rod 83 is a paper table 111, which is pivotedthrough ears 112 located as at 113, and is attached by a spring .114 toa pin 115 that is carried by the arm 84. Said table has cutouts 116,with the upper and lower edges bent rearwardly, and worksheets willtherefore not be caught by said edges. Ears 117 have set-screws 118, and

as an adjustthrough which said table is guided, and also have additionalguides in the form of rollers 121. Said table supports a bar 122, whichis attached by rivets blocks 123. Said bar has a plurality of dishedrecesses 124' with can be registered.

The diameter .ofthe lug 40 is less than the width of the space 125between tines 126 and 127, and provides a lost-motion connection for alever 128 having a hub 129, mounted on a stud 130, which is carried byone of the brackets 30. Said lever 128 has a cam-edge 131 and a hookedend 132, to loosely and partially encompass theroller Said hookaccomplishes the dual purpose of preventing the and of affording a propto hold the roller in raised position. Said lever is loosely mounted, sothat its overbalanced weight will tend to keep it in normal position.

that also hold' spacingwhich the convex ends 106 1 terposed work-sheets.Said portions 135 havetheir lower ends flared from said jaws, for theeasier insertion of said worksheets. A

type-bar 137 is shown, to illustrate the nearand the associated partsare not disturbed.

' release the ness of the typing line to the sets of clamps and a rearside-edge gage is indicated by 138. In operation, the parts willnormally lie as illustrated in Figures 1 and 4. In such positions a workweb or pack 10 is rear-inserted and deflected between the platen and thepressure-fingers 13. I The work-pack is further advanced, and is ledbetween the parts 67 and 135, which are referred to as the lowerstationary or closed clamps. As the latter are normally closed, thefinger-lever 62 is moved to rock the cam 60, which, in a well-knownmanner, depresses and holds the cam-lever 59 to rock the lower rod 45with the attached pressure-arms 66, and the latter will swing the jaws67 and leave open saidlower clamps. The work-pack is thenadvanced abovethe parts 104 and 122, which are referred to as the upper open orweb-feeding clamps, and at this stage are normallyopen. Thecfinger-lever62 is released, and is restored to its normal position through tensionof the springs 57 and 73. In its restored position said lever is held,through engagement of the recess 63, by the leaf-spring 64. The releaseof said lever causes the lower clamps to again close, and to grip thework-pack.

When the finger-lever 62 is operated the lever 54 will be rocked, andits ear 55 will swing up and away from the lifting arm 44 With the lowerclamps closed, as last above mentioned, a linemay be typed, after whichthe sheets areline-spaced. To accomplish this, the spacing lever 36 ismoved a full stroke to the right, from end to end of the guide 38. Thisforces the slide-bar 28 to the rear, and, through the lug 40, startsswinging the cam 131. Meanwhile'the trip 39 .will cam and raise tl1e\jack-lever- 42. As the jack-lever is forced up, the parts assume thepositions shown by Figure 2, in

which the roller 74 has cammed the lever 76 and'swung forward thepressure-arms 102 to jaws 104. The latter, through te1ision of theirsprings 110, will press against the work-pack, which will thus be firmlyheld by the upper clamps. It will be noted that at this stage the lowerclamps also grip the work-pack. Further travel of the slide-bar winds upand increases the tension of the springs 110 through the further forwardswinging of said pressure-arms, as the parts gravity,

revawe assume the positions shown by Figure 3, where the lower clampshave been opened through the'rearward swing of the pressurearms 66,which operate thejaws 67 to release their grip on the work-pack.

In certain positions of the parts, between those shown by Figures 3 and7, the cam 131 will engage and raise the roller 95. This movementelevates the upper clamps, which are carried by the swingable arms 85and 86,

and pulls up the work-pack to line-space it. 1

of the jack-lever by the trip 39. Through such position of said steppinglever, the lower clamps are held open and the upper clamps are heldclosed, as the line-spacing movement is accomplished. During the latter,the trip 39 and cam. 131 will travel to the position shown in saidfigure. A fur ther slight rearward movement of the trip 39 kicks freesaid lower seat 52, and said stepping lever 50 drops. The upper seatthereupon engages the rest 26 through tension of the spring 53. ,Saiddropping-occurs partly through gravity and partly through tension of thespring 57 and effects closure of the lower clamps.

As the stepping lever 50 drops, the upper clamps are held in raisedposition through the roller 95 and the hooked end holdingpermits thesuccessive closing of the lower clamps and opening of the upper clampsbefore the latter drop to normal po sition. Such jaw-movements of therespective clamp-sets occur as the parts move out of the positions shownin Figure 7, and into the positions shown by Figure 6, During theensuring restoration of the slide-bar 28, the upper clamps open throughtension of the spring 114, asthe lever 76 is released through droppingof the lifting arm 44. As said roller is released from said hooked endthrdugh thev lug 40, the upper clamps will drop, through to the normalpositions shown in Figure 1'. p x

In Figure 6 the slide-bar 28, trip 39 and lug 132. Such 40 are shownboth by solid and dotted lines.

The latter indicatethe extreme rearward positions of said parts, whilethe former show the same as they move toward restored positions. By suchdual positioning, it is illustrated, in particular, that said lug 40 ispro- I vided with lost motion between the tines 126 and 127. Thispermits more time in which the lower clamps may close, and the upperones may open before the latter are dropped. Additional time is gainedfor the foreserves a dual purpose,

same purpose, through the lingering disengagement of the roller 132 asthe latter is swung roller. 1

The lost-motion provision last above described has another benefit, inthat the momentum thereby. gained helps the lug 40 to disengage thehooked end and roller as the slide-bar is restored. For this reason alighter spring 33 may be used, which makes easier the operation of thespacing lever. Due to the rollers 121, the table 111 with the attachedbar 122 is so guided that the upper clamps pull the work-pack throughthe lower clamps in practically one plane. As the lower clamps registerwith this plane, the latter is not upset when the pack is gripped bysaid clamps. For this reason the pack will remain taut between the lowerclamps and the pressurefingers 13, and type-impressions will beclearcut.

During the restoration of the slide-bar, the trip 39 will idly passunder 42. The latter will then be restored to the normal position shownin Figure 1, through tension of the spring 53. The latter thereinconnecting with the aforementioned stepping lever 50. A dual function isperformed also by the spring 114, which holds the table 111 against therollers 121, and helps to restore the upper clamps from the positionsshown inFigure 7 to that shown by Figure 6. In the latter, also, isillustrated that the throw of the lever 128. In such position, too, saidlever acts as a rear stop for the slidebar, through abutment of thetine126 and the lug 40.

The slide or driver 28 closes the clamps 106 by means of cam 42 andlever 44, the latter operating the clamps 67 As the lever 44 is furtherelevated, the cam? 5 drives the link from under said 79 to the right,and closes the clamp 106. The

driver 28 also operates the cam-lever 131. A second lever 93 is swung bycam 131. The clamps 106 are connected to saidsecond lever 93 to belifted thereby for line-spacing the web.

The latch 50, being raised bythe lever 44, is caught upon the projection26. The pin 39 (which at first operated the cam 41) finally engages thelatch 50 at the conclusion of,

the driver stroke, and forces said latch off from the pin 26, so thatall the clamps may return to their normal positions-independently of theweb. The spring 33 will return the driver 28 and the line-space handle36.

It will be seen that at one stage, just before the web advances, all ofthe clamps are momentarily closed upon the web, as at Figure 2. Atanother stage, at the conclusion of the web-feeding movement, all theclamps are again momentarily closed upon the web;

Hence the web is at no time free from clamps, and cannot becomedisarranged.

95 by the hooked end the jack-lever hooked end 132 prevents overdoes notthe web It will be noted .that the lever 36 line-space the platen, butline-feeds around the stationary platen during a carriage-returningsweep of said lever; that the gripping of the web by either set ofclamps anticipates the release of the web by the other set of clamps andthe loose plies are at all times under the gripping control of one setof clamps; that the stationary clamps are opened. and reclosed duringthe forward or carriage-returning sweep. of the lever 36; that theweb-feeding clamps are closed upon the web, actuatedto line-feed the weblocked during the forward stroke of the lever 36 to give ample time toreclose the stationary clamps upon the loose plies of the web before theweb-feeding clamps'release the web on the initial return sweep of thelever 36 that the loose plies are printed upon a letter-fed platen thathas no line-spacing connections, and the loose plies are drawn andspacing. lever 36 and self-retractible to a web-clamping state whenreleased by means controlled by the sweep of said lever; that theweb-binding gripof the clamps is. made uniform by individually-adjustedspring-tension, and not from pressures derived'from a variably-actuatedline-feeding lever; and that the loose webs are manifolded and linefedin a flat state because the direction of. the web-feedingpull is tangentto the typing line of the platen.

In a typewriting machine, the combination of a carriage having aplaten around which the loose "plies of a work-web are to be manifoldedand fed line by line, a plurality of web-controlling devices on thecarriage, at the delivery side of the platen, operable to prevent therelative creeping of the loose plies, said web-controlling devicesincluding stationary clamps on the carriage normally binding the looseplies together while manifol'ding, normally open grippers swingable uponthe carriage for line-spacing the web around'the platen, and manualmeans operable by a continuous movement thereof to open the stationaryweb-binding clamps to release the manifolded web, close the grippers tobind the plies together before their release from the clamps, swing thegrippers to line-space the manifolded web around the platen, close thestationary clamps to rebind the line-spaced plies together, and releasethe web from the grippers.

16. In a manifolding /'mechanism for a typewriting machine, thecombination of a letter-feeding carriage having a stationary platenaround which the loose plies of a multiplely work-web may be drawn to belinespacehl, web-controlling means on the carriage, at the delivery sideof the platen, to prevent the relative creeping of the loose plies oneupon the other during the manifolding and the repeated line-spacing ofthe web, said Web-controlling means including a frame on the carriageoperable to hold the web stationary, and also including a frameswingable upon the carriage, operable to line-space the web, each framehaving-means to independently clamp the loose plies of the web together,and a line-space lever having means to operate theweb-clamping means inalternation, sothat the clamps-onthe stationary frame will bind theplies of the web together while being manifolded and the clamps on theswingable frame will bind the plies of the web together while the web isline-spaced by the swingab e frame, the latter" being returnable tonormal position independently of the web.

17 In a manifolding mechanism for a typewriting machine having aletter-feeding carriage and a stationary platen around which the looseplies of a multiple-ply workweb maybe drawn, the combination of meansfor line-spacing the work-web without causing the loose plies of the webto creep one over the other during the manifolding of the plies and therepeated line-spaclng of the web, said grippers on the carriageswingable in a linespacing direction, a reclprocable line-spacing 8 i Ievon e lever on the carriage, and mechanism actuated by the one-wayswing of the'line-space' lever, operable to release the web from theclamps, bind the plies between the grippers to line-space the web aroundthe platen, and restore the web to the control of the clamps, the returnof the line-space lever operating to release the web from the grippers.

18. A paper-feeding mechanism for typewriting machines having aletter-feeding carriage and a stationary platen around which the looseplies of a web are to be fed, including a line-spacing lever on thecarriage, clamps on the carriage operable by said lever to clamp theloose plies together and manually operable to line-space the Web,holding clamps on the car'riageoperable to clamp the loose plies whennot being line-spaced, mechanism actuated by the line-space leveroperable to open the web-holding clamps before the webfeeding clampsbecome operative to line-feed.

the web and operable to re-close the webholdin clamps before the web isreleased by the we -feeding clamps at the end of a linespacingoperation, and a cutting blade on the carriage across which the looseplies may be drawn to sever the manifolded plies, at will,

fromthe clamped-together web of plies.

19. The combination of a platen, a linespace lever, a driver driven bysaid line-space lever, normally closed stationary work-holding clamps,normally open movable workholding clamps, means operable by said driverto effect the closing of the normally open clamps, means to enable saiddriver thereupon to open the normally closed clamps, means alsocontrolled by said driver to latch the movable clamps in closed positionand the stationary clamps in open position, a camlever operated by saiddriver, a second lever swung by said cam-lever, said movable clampsbeing connected to said second lever to be moved thereby forline-spacing the Web, means to enable said driver at the conclusion ofits drive stroke to unlatch the clamping de-- vices, and thereby causethe stationary clamps to close and the movable clamps to open, andpermit the return of the movable clamps to starting positionindependently of the web, and a spring to return said driver to normalposition, said movable clamps bein g returnable to normal positionsindependently of said web.

20. iMechanism according to claim 19, in which said second lever isprovided with an automatic lock to prevent overthrow of the clamp-mQvinglever.
